You don’t have to get out of your pajamas to visit the Sacramento Zoo this Christmas Eve. Admission will be free from 10 a.m. to 1:30 p.m. on Dec. 24, and everyone will be in their most playful PJs to kick Christmas Eve off in style. While you’re out, pop over to Fairytale Town from 10 a.m. to 2 p.m., where admission is also free on Christmas Eve.
